A wiper device for an automotive vehicle.

摘要

The circuit includes reversible driving motors (10) for driving a pair of wiper assemblies (1, 2) in first and second directions alternatively. Each driving circuit (42, 43) includes a switching means and a means (15-20) for detecting both ends of the wiper blade motions in the first and second directions. The switching means is operative to switch direction of an electric power supply to an electric motor when the detecting means detects the end of wiper blade motion. Each driving circuit is connected to both of switching means so that it can reverse the power supply to the driving motor when both of switching means detect the ends of the wiper assembly motion.
